Abstract:A number of permanent runoff controls were constructed along new highways in the Edwards aquifer recharge zone, with their performance monitored since the highways opened. The control systems consist of a hazardous material trap, a sedimentation basin, and a vertical sand filter. The filter, constructed as part of the wall of the basin, is held in place with filter fabric and rock gabions. Numerous problems have been documented with these systems, mostly in conjunction with the performance of the vertical sand filter. Sedimentation was the most important pollutant removal mechanism for the runoff control systems. Modifications of runoff control systems that focus on extending the detention time of the basins may be more effective in controlling suspended solids in runoff than enhancing the filter performance.
